Answer:
y= 30°
Step-by-step explanation:
y° +y°+y°+y°+y°+y°=180°
6y°=180°
y=30°
Answer:
y = 60
Step-by-step explanation:
The exterior angles of a regular polygon add up to 360. Try drawing a square which has exterior angles = 90 degrees or an equilateral triangle which has an exterior angle of 120.
Formula is
Exterior angle = 360 / number of sides
number of sides = 6
Exterior angle = 360/6 = 60
x is the supplement of y
x + y = 180
x + 60 = 180 Subtract 60 from both sides
x = 180 - 60
x = 120

Answer:
18+12.125π units²
Step-by-step explanation:
The diameter of the semicircle can be found by the use Pythagoras theorem.
Δx²+Δy²=d²
Δx=3--1=4
Δy=3--6=9
d²=4²+9²
d=√(16+81)
Area=πr²/2
=π×(√(16+81)/2)²÷2
=[π×(97)/4]/2
=97π/8
=18+12.125π units²
97π/8 is equivalent to 18+12.125π units²

Answer:
2,∞
Step-by-step explanation:
For the range, x2 takes its minimum at x=0 , so putting in x =0 gives y=√x2+4=√0+4=2 therefore making the range [2,∞).
The answer that I got was y=105 Hope this helps!
Wow what grade are you in that seems hella confusing!! I feel bad for you!
